One upgrade that can give you some added power and throttle response (and it's free) is to advance your timing 2 degrees.
Most of those power adders on eBay are gimmicks. I really wish they did work, but unfortunately all they do is add a resistor across some wire which makes the car feel like it's driving better.
The reason why those ECM reprogrammers are so expensive is because they go through years of research to find out how the factory computer works and how it mixes the fuel.
Here's the key to those eBay power adders: If you find one and it has your vehicle make, model and year in the auction title, search that same auction title without the make, model and year. If you get a million results for every vehicle that ever existed, it's a gimmick.
